Quick and painless port out to Tello US
You can use your phone and sim from ringplus. only took me 2 minutes. plans are affordable and customizable (I got 500 min, unlimited text, and 1gb for $24). Port out process was easy. The account number is your phone number, and the pin/passcode is the 6 digit MSL found on your dashboard under manage device. Coverage is with sprint. Not much more you can ask for (not even an activation fee).
